The third eastern Pacific tropical system of the year will threaten southern Mexico with flooding rainfall into the middle of the week.“Late Sunday afternoon, an area of tropical low pressure south of the Gulf of Tehuantepec became better organized into Tropical Depression 3-E,” said AccuWeather Senior Meteorologist Frank Strait.
Warm ocean waters and favorable atmospheric conditions allowed the system to strengthen, becoming Tropical Storm Calvin Monday afternoon. Calvin weakened back into a tropical depression Monday night after making landfall.
“Regardless of the strength of this system, heavy rain will impact much of southern Mexico through the middle of the week,” said AccuWeather Senior Meteorologist Matt Rinde.
Over the mountainous terrain of the Sierra Madre del Sur, the system will continue to weaken and dissipate, while still threatening flooding rainfall.
“The primary concern with this feature is going to be the potential for excessive rainfall over the southern part of the Mexican state of Oaxaca, as well as southeastern Guerrero and southwestern Chiapas,” said Strait.
